Application filed. November 28%, 1915. Serial No. 62,991.

I To all whom it may concern Be it known that I ABRAHAM BROUNE, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented newand useful Improvements inCollapsible Window- Guards, of which the following 1s a speclfication.

This invention relates to improvements 1n window guards and particularlyto such as are adapted to be disposed in the windows of dwellings, whereit is desirable to prevent untoward accidents occurring to children andothers from falling outwardly therefrom.

The principal object of the invention is to provide a device readilyattachable to any common form of window whatever, having means wherebyit may be expanded or retracted to suit any window frames of commonconstruction.

A further object is in the provision of means whereby the protectivebars may be elevated into operative position or depressed so as topresent a clear space through the window opening.

A. still further object is to provide means whereby the protective barsare positioned and held under tension outwardly beyond the windowopening so that the sill of the same may be used for such purposes asare desired and which will permit the bending or limited leaning forwardof a person without danger.

Those and other objects, such as neatness of appearance, low cost ofconstruction, and general adaptability, are attained by the novelconstruction and combination of parts hereafter described and shown inthe aclib companying drawings, forming a material part of thisspecification, and in which F igure'l is a front elevation of a window,looking from the outer side thereof and having a guard attached, theparts being in operative position. Fig. 2 is a similar view, but showingthe guards in a lowered or depressed position, leaving the window spaceopen. Fig. 3 is a cross sectional view, taken on line 33 of Fig. 1,showing the guard supports in their outermost position. Fig. 4 is anenlarged sectional view, showing the corner securing means as extendedoutwardly to their extreme limit. Fig. 5 is an enlarged longitudinalsectional view, taken through the engaging means of the upper barelement. Fig. 6 is a further enlarged view, showing in detail fragmentsof the guard bars and operating means and Fig. 7

is a fragmental side elevation of the upper end of vertical guidemembers.

The invention, as disclosed in Figs. 1 and 2, is seen to be attached tothe exterior of an ordinary window by means of the flanges 10, the lowerof which are secured to the frame of the window, immediately. above thesill while the upper flanges are midway of the window, approximately atthe bottom of the upper sash; these flanges have rigid stems 11, andslidable on the stems are hollow elbows 14. In order to maintain theelbows on the stems, the latter have slots 12 formed lengthwise andslidable in the slots are pins 15 set rigidly in the elbows, near oneend, the pins also operating to maintain the elbows so that their inner,facing ends 18 are in alinement. Stifi' coiled pull springs 17 encirclethe stems 11 and have their ends firmly engaged respectively with theflanges and extreme ends of the elbows so as to draw the latter inwardtoward the window when extended. In the other opening at the end 18 ofthe elbows are received the stems 20 of the supports 21, the stems beinggrooved annularly so that the points of the set screws 19 may seattherein and be firmly held. While the foregoing specifically describesthe construction shown in the drawing, it will be obvious that othersupports difi'erently constructed may be used. These supports arerigidly affixed to the tubes 30 extending vertical, parallel with eachother and wit-h the window.

A series of horizontal bars 22 are provided at their ends with ringelements 23, adapted to freely slide upon the vertical tubes 30 and arenormally constrained toward each other by reason of the links 24,pivoted to them and which are hinged as at 25, at their opposite end andprovided with springs 26, exerting their tension to close the linkstogether in the manner of a pair of shears, except the last link whichis pivoted to the lower support.

The upper element 28, in addition to its encircling ring about the tube,contains plunger rods 29, movable outwardly by reason of the cam 33opposing the spiral push springs 34, the ends of the rods 29 beingadapted to engage with a plurality of spaced openings 32 formed throughthe wall of the tubular members 30. Thus by turning the cam 33, which isprovided with an opening zontal rods disposed across the window 31 toreceive a ke by which it is operated, the rods 29 will e retracted,allowing the bars 22 to be raised or lowered as desired, and held inposition by again turning the cam 33, allowing the springs to push theplungers 29, into engagement with others of the openings 32 .in the tube30.

Having thus described my invention, what,

I claim as new and desire to secure by Letters Patent is-:

, 1.7 In a window guard, a plurality of horispace, guide bars upon whichsaid rods move vertically, supports for said ide bars, said su portsbeing rigidly attac ed to the outsi e of the window frame, and resilientmeans interposed between said supports and said bars permitting saidbars to move 7 eing pivoted together, means combined with each of saidpairs of links adapted to draw said rods closely together, and means forengaging the uppermost of said rods with said support bars at difierentheights relative to the window space.

In testimony whereof I have signed my name to this specification.

. ABRAHAM BROUNE.
